ATHLETIC SPRING EXERCISER.

Application filed October 30, 1925.

This invention relates to improvements in spring supporting means forshoes, the general object being the provision of spring members disposedbetween companion plates, one of which being adapted for engagement witha ground surface and the other for association with the sole of a shoe,whereby the operator may attain a great rate of speed in racing, walkingand jumping owing to the spring act-ion giving a momentum equivalent tothat obtained from the springiness experienced in walking.

A further object of my invention resides in the provision of armspivotally mounted upon the inner sides of the plates and having theirremaining ends correspondingly associated to attain the desired springand rebound.

1V ith the above and other objects in view, the invention furtherconsists of the following novel features and details of construction, tobe hereinafter more fully described, illustrated in the accompanyingdrawing, and pointed out in the appended claims.

In the drawing:

Figure 1 is a side elevation of my invention as applied.

Figure 2 is a longitudinal sectional view taken on line 22 of Figure 1.

Referring to the drawing in detail, wherein like characters of referencedenote corresponding parts, the reference character indicates a shoe ofthe usual and well known construction which forms no part of the presentapplication for latest patent but which is merely shown for purposes ofillustration in bringing forward the novel advantages of the aboveentitled invention when used in conjunction therewith. The inventionresides in the provision of com pa-nion plates 11 constructed after themanner and closely resembling the formation of a shoe sole, one of whichis secured to the shoe 10 by strips 12.

Mounted for pivotal movement between spaced parallel apertured cars 13carried upon the inner sides upon the companion plates 11 are arms 14and 15 respectively. The-arms 14: are relatively fiat and extendupwardly from the upper side of the lowermost of the plates 11 andterminate in apertured portions upon their free ends, the purpose ofwhich will be presently apparent. The adj acent ends of the arms 15 arereversely disposed and terminate to provide bifurcated Serial No.65,838.

portions 16 upon the free ends thereof and which receive the aperturedends of the arms 1 1 therein. Pivot pins 17 carried by said bifurcatedportions 16'pivotally associate the adjacent ends of the arms. Both setsof arms provide extensions 18 which are arranged at an inclination withrespect to the normal positions of the arms and which are adapted toengage the corresponding inner sides of the companion plates 11 tonormally position the latter as illustrated in Figure 1 of the drawingand to check the rebound ac tion of the plates in amanner to bepresently described. Pairs of spaced aligned clips 19 are carried uponthe inner opposed faces of the plates and which are adapted toreceivetherein the respective ends 20 of compression springs 21. Said springsare of sufiicient size. weight and proportions to give a desired springaction relevant to the weight of the person employing the device.

In the mode of operation of the invention, subsequent to applicationupon a shoe and upon alternately compressing the springs- 21 andrelatively moving the plates one toward the other a spring action whilewalking and spring rebound while jumping will take place, whereby agreat rate of speed may be attained through the use and operation of theabove entitled invention.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having thus described my invention what is claimed is:

1. A spring support for use upon shoes comprising companion plates, oneof said plates having means for attachment to the sole of the shoe,spaced parallel apertured ears carried upon the inner sides of theplates, arms pivotally mounted between said ears and having theiropposite ends disposed in juxtaposition, one set of arms terminating inbifurcated end portions for pivot-ally connecting the adjacent end of acompanion arm, andccmpression springs interposed between the companionplates.

2. A spring support for use upon shoes comprising companion platescorresponding to the configuration of the soles thereof, one of saidplates having means for attachment to the sole of the shoe, ears carriedupon the opposed faces of the plates, arm members pivotally connectedWith said ears adjacent the outer ends thereof, the free ends of one setof arms terminating in bifurcations for pivotally associating theadjacent end of the companion arm therewith, compression springsinterposed between said plates, and angularly disposed extensionscarried upon the first mentioned ends of the arms adjacent theirassociation with the ears and adapted to engage the inner sides of theplates to restrict the rebound of the device While in use.

In testimony whereof I affix my signature.

ANTHONY C. SCHAD.
